When CDR is activated, a CPU utilization increase of 2% is typical, 4% if both CDR and CMR are
activated.
Perfmon Counters
Table 3-5 lists some equivalent perfmon counters between Cisco Unified CM Release 4.x and Release
5.x and later.
Integration with Uninterruptible Power Supplies (UPS)
As of Cisco Unified CM Release 6.0(1a) and later, the server supports integration with certain models
of APC UPS for certain MCS 7800 models. Previous server releases rely on an external script monitoring
the UPS and issuing the Cisco CLI for graceful shutdown. See the release notes for Cisco Unified CM
6.0(1b) for more details at
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/6_0_1/cucm-rel_note-601b.html.
Note Native hardware out-of-band management such as HP iLO or IBM RSA II cannot be used for graceful
shutdown of Cisco Unified CM.
Native Hardware Out of Band Management (OOB)
The supported features of HP iLO and IBM RSA II are enabled for the following areas:
• CPU status/utilization
• Memory status/utilization
• System components temperatures
• Fan status
• Power Supply status
• RAID & disk status
• Network status including NIC
• Operational status, including instrumentation of system/kernel status and data dumps following
major system issues, indicating nature/type of the operational problem and degree of severity.
